FACILITATING THE SEPARATION OE GARLIC FROM WHEAT.

Patented Dec. 20, 1910.

Application filed. February 18, 1910. Serial No. 544,590.

T 0 all whom it may concern:

Be it known that 1, JOHN l VILLIAM Mc- GEHEE, of Martin, in the countyof lVeakley and State of Tennessee, have invented certain new and usefulImprovements in Machines for Facilitating the Separation of Garlic fromlVheat; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others slrilledin the art to which it appertains to make and use the same.

This invention relates to machines for facilitating the separation ofgarlic from wheat.

The seed of garlic or onion is approximately the size and weight ofwheat grain and it is therefore not feasible to attempt the separationof one from the other by means of the ordinary screening operations noris it desirable to attempt the crushing of the garlic by passing themixed garlic and wheat between rolls. It is necessary how ever, in orderto separate the garlic from the wheat that the garlic shall be crushedwithout mashing the wheat, in order that it may be in condition toremove it from the wheat by subsequent cleaning methods which mayinvolve the use of air blasts or other devices commonly employed ingrain cleaning or scouring mechanism.

The object of my invention is to provide means whereby the mixed wheatand garlic can be subjected to a pressure which will be sufficient tocrush the garlic through the medium of the forcible engagement of thewheat grains therewith while the mixture of wheat and garlic aresubjected to agitation simultaneously with the pressure above alludedto.

A further object is to so construct the machine that the degree ofpressure to which the mixed wheat and garlic are subjected duringagitation, can be accurately regulated.

With these objects in view the invention consists in certain novelfeatures of con struction and combinations of parts as hereinafter setforth and pointed out in the claims. or In the accompanying drawings,Figure 1 is a longitudinal sectional view of a machine embodying myimprovements. Fig. 2 is a transverse sectional view of the same,

i and Fig. 3 is a longitudinal sectional view illustrating a modifiedconstruction embodying my invention.

1 represents a cylinder or container provided at or near one end with aninlet spout or hopper 2 and in proximity to the other end with an outletor discharge opening 3 which communicates with a discharge duct r. Theoutlet or discharge opening 3 is normally closed by means of a valve orgate 5 held in position by yielding means, such as a spring 6. Thisspring is secured at one end to the cylinder 1 and in order to regulateits tension and consequently the degree of pressure within the cylindernecessary to open the valve, an adjusting device 7 is attached to thecylinder and made to engage the spring at a point between the ends ofthe latter.

A shaft 8 is mounted in suitable bearings at respective ends of thecylinder and to this shaft a worm conveyer 9 is fixed. The conveyer 9extends from the inlet end of the cylinder to a point somewhat removedfrom the opposite end so that at the outlet end of the cylinder, achamber 10 is formed and this chamber communicates directly with theoutlet or discharge opening 3 in the wall of the cylinder. The outerwall of the chamber 10 is formed by means of a disk 11 rigidly securedto the shaft 8 in proximity to the adjacent end wall of the cylinder,and provided with knobs or projections 11.

One end of the shaft 8 is provided with a pulley 12 for theaccommodation of a belt from any suitable source of power.

Mixed grain or garlic and onion will be fed through the inlet spout orhopper into one end of the cylinder and will be moved by the co veyertoward the opposite end of the cylinder and pressed against disk 11 atthe opposite end of the cylinder. The disk 11 which forms an abutmentfor the mixed wheat and garlic, being secured to and rotating with theconveyer worm 9, will prevent clogging of the grain in the chamber 10and undue friction of the shaft and its bearings,-both of which resultsmight otherwise occur to a greater or less degree if the disk 11 wereomitted and the fixed end wall of the cylinder were utilized as one wallof the chamber 10. The yielding valve or gate 5 will hold the mixedgrain and garlic forced forwardly by the worm conveyer to the chamber10, until sufficientpressure has i been developed within the cylinder tocause the engagement of the I while both the wheat and garlic are inagitation, with the garlic to tear and crush the garlic. After thedegree of pressure within the cylinder shall have exceeded thatnecessary to effect the tearing and crushing of the garlic by theengagement therewith of the grains of wheat during agitation, the valveor gate 5 will be forced from its seat and the mixed wheat and crushedgarlic will be permitted to escape through the discharge opening 3 tothe duct 4C,by which latter it will be conveyed to suitable cleaningmechanism for ren'ioving the crushed garlic and hulls from the wheat.

In the construction shown in 3 the cylinder is provided at both of itsends with inlet spouts or hoppers 13 and instead of fori'ning an openchamber such as 10 at one end of the cylinder, an open chamber i l isformed at the center of the cylinder between the inlet ends of right andleft hand worm conveyers 15 secured to the shaft 16. In this modifiedconstruction the discharge opening 17 is located centrally bGLTVEQIl theends of the cylinder and communicates with the open chamber l l betweenthe inner ends of the respective worm conveyors 15. The discharge outlet17 is closed by a valve or gate 18 normally pressed to its seat by anadjustable spring 19, the same as with the construction shown in Fig. 1.In the use of the modified construction shown in Fig. 3, the mixed grainand garlic is fed into both ends of the cylinder and will be agitatedand moved toward the central chamber 14. The movement of the mixed grainand garlic in opposite directions from respective ends of the cylinderto the central chamber l l will cause suflicient pressure to effect thecrushing and tearing of the garlic by the action thereof of the wheatgrains,-each of the worm convey its 15 in this case acting as anabutment for the other in substantially the same manner as the disk 11acts as an abutment for the mixed grain and garlic forced toward the endof the cylinder by the conveyer as shown in Fig. 1.

Any suitable cleaning mechanism or device might be employed and in thedrawings I have merely indicated such a device diagrammatically at 20.

Various slight changes might be made in the details of construction ofmy invention without departing from the spirit thereof or limiting itsscope and hence I do not wish to restrict myself to the precise detailsherein set forth.

Having fully described my invention what I claim as new and desire tosecure by Letters-Patent, is,

1. A machine for facilitating the separation of garlic from grain,comprising a congrains of wheat.
